(W Sladden Engineering 6782 Stanton Ave., Suite A, Buena Park, CA 90621 (714) 523-0952 Fax (714) 523-1369 39-725 Garand Ln., Suite G, Palm Desert, CA 92-211 (760) 772-3893 Fax (760) 772-3895 June 28, 2006 Project No. 522-4402 06-06-667 Trans West Housing, Inc. 10721 Treena Street, #200 San Diego, California 92131 Project: Griffin Ranch Residential Development SEC Avenue 54 and Madison Street La Quinta, California Subject: Report of Observations and Testing During Rough Grading Ref: Geotechnical Investigation Report prepared by Sladden Engineering dated August 17, 2004; Project No. 544-4402, Report No. 04-08-571 Geoted-mical Update report prepared by Sladden Engineering dated December 2, 2005; Project No. 544-4402, Report No. 05-11-1133 Summarized in this report are the results of in -place density tests performed at the subject site during the rough grading of the building pads along with pertinent observations. The subject site is located on the south east corner of Avenue 54 and Madison Street in the City of La Quinta, California. The building pad areas were overexcavated to a depth of at least 3 feet below existing grade or 4 feet below pad grade, whichever was deeper. The previously removed native soil, native soil obtained from cut areas of the site and import soil were placed in thin lifts at near optimum moisture content and compacted to at least 90 percent relative compaction Observations and field testing was performed from March 13, 2005 to April 10, 2006. Testing indicates that after reworking areas of low density, a minimum of 90 percent relative compaction was attained in the areas tested. The passing test results indicate compliance with the project specifications at the tested locations and depths but are no guarantee or warranty of the contractors work. June 28, 2006 -2- Project No. 522-4402 06-06-667 Field Tests: In -place moisture/density tests were performed using a nuclear density gauge in accordance with test methods ASTM D 2922 and ASTM D 3017. A total of 509 density tests were performed by Siadden Engineering personnel during grading. The approximate test locations are indicated by lot number and on the attached plans and test results are summarized on the attached data sheets. Laboratory Tests: The moisture -density relationships for the tested materials were determined in the laboratory in accordance with test method ASTM D 1557-91. Allowable Bearing Pressures: The structural values recommended in the referenced Geotechnical Investigation report prepared by Sladden Engineering remain applicable for use in foundation design. Conventional shallow spread footings should be bottomed into properly compacted fill material a minimum of 2 feet below lowest adjacent grade. Continuous footings should be at least 12 inches wide and isolated pad footings should be at least 2 feet wide. Continuous footings and isolated pad footings should be designed utilizing allowable bearing pressures of 1500 psf and 1800 psf, respectively. The recommended allowable bearing pressures may be increased by one-third for wind and seismic loading. The bearing soils are non -expansive and fall within the 'very low" expansion category in accordance with Uniform Building Code (UBC) classification criteria.
